Renaming or Removing ClientRegistry.blob from Steam

The ClientRegistry.blob file, which resides in the root of your Steam folder, is essentially a binary/cache file used to store preferences and other settings. This file can sometimes become corrupt and cause (over 25% of Steam related) problems. Thankfully, we're going to walk you through how to fix this.

Locating Your ClientRegistry File

Your ClientRegistry.blob sits inside the root of your Steam folder.

Windows XP, Windows Vista, and Windows 7 Users

Browse to "C:\Program Files\Steam" (or "C:\Program Files (x86)\Steam" if you're on a 64-bit PC).

Mac OS X Users

Browse to "/Users//Library/Application Support/Steam"

Fixing Your ClientRegistry File

Don't be worried, there's nothing fancy about how to "fix" your ClientRegistry.blob file. All you need to do is:

1. ensure that Steam isn't running (and close it if it is)
2. make a backup copy of the file - you don't have to place this backup in the Steam folder like Steam Support suggests you should
3. remove the original version of the ClientRegistry.blob from your Steam folder
4. restart Steam
